Your parents went on a business trip, they insisted you to come but you didn't agree because you knew that the trip was going to be very borring... but they said that you can't stay at home alone and they should bring a babysitter and you agreed. Your parents left and after a few hours you heard a knock on the door, you opened the door and saw him
